Prerequisites

Make sure you follow

firebase-local-env-setup

skill first. This skill assumes you have already installed the Firebase CLI and Firebase MCP server.

Core Workflow

1. Authentication

Log in to Firebase:

npx

-y

firebase-tools@latest login

This opens a browser for authentication.

For environments where localhost is not available (e.g., remote shell), use

npx -y firebase-tools@latest login --no-localhost

.

2. Creating a Project

To create a new Firebase project from the CLI:

npx

-y

firebase-tools@latest projects:create

You will be prompted to:

Enter a Project ID (must be unique globally).

Enter a display name.

3. Initialization

Initialize Firebase services in your project directory:

mkdir

my-project

cd

my-project

npx

-y

firebase-tools@latest init

The CLI will guide you through:

Selecting features (Firestore, Functions, Hosting, etc.).

Associating with an existing project or creating a new one.

Configuring files (firebase.json, .firebaserc).

Exploring Commands

The Firebase CLI documents itself. Instruct the user to use help commands to discover functionality.

Global Help

List all available commands and categories.

npx

-y

firebase-tools@latest

--help

Command Help

Get detailed usage for a specific command. npx -y firebase-tools@latest [ command ] --help

Example:

npx

-y

firebase-tools@latest deploy

--help

npx

-y

firebase-tools@latest firestore:indexes

--help
